Mohamed G. Atta, MD, MPH, is Associate Professor of Medicine at Johns Hopkins University School of Medicine in Baltimore, Maryland, and Medical Director of the Dialysis Center, DaVita Health Care in East Baltimore, Maryland. A graduate of Mansoura University School of Medicine in Egypt, he completed his internship and residency training in various locations including the Urology and Nephrology Center at Mansoura University, Cabrini Medical Center in New York, and Johns Hopkins University School of Medicine. Dr Atta received his MPH degree from Johns Hopkins Bloomberg School of Public Health in 2005.

Dr Atta is a member of the Health Disparity Committee at the Department of Health and Mental Hygiene in Maryland, the Scientific Council on Kidney of the American Heart Association, the International Society of Nephrology, and the American Society of Nephrology. Dr Atta has participated as principal investigator in several studies and serves as a peer reviewer for the Archives of Internal Medicine, American journal of Medicine, Kidney International, Clinical Journal of the American Society of Nephrology, American Journal of Kidney Diseases, Clinical Infectious Disease, and Journal of Infectious Diseases. He authored or co-authored numerous articles and abstracts published in Genomics, the Journal of Biological Chemistry, Clinical infectious disease, American journal of Medicine, and American journal of transplantation, the Journal of Ultrasound in Medicine, Clinical Journal of the American Society of Nephrology , American Journal of Kidney disease, Nephrology Dialysis Transplantation, and Kidney International, among others.

 Past Activities:

• Genetic cloning of the human gene that encodes the sodium myo-inositol cotransporter (SMIT). This transporter is essential for cell volume regulation in response to hypertonicity. 
• Studying the transcriptional regulation of the human SMIT gene.
• Subsequently my focus was to explore the potential role of protein phosphorylation in regulating the activity of osmolyte transporters in response to hypertonic stress.
• A clinical prospective cohort study to determine the incidence of vancomycin resistant enterococci (VRE) in outpatient dialysis patients and the association of vancomycin use with the development of VRE in this population.
• In collaboration with Dr. Fine, we were able to determine the utility of transjugular kidney biopsy in high-risk patient.

Current and Future Plans:

• At present, I’m studying kidney diseases in patients with HIV infection.
• Identifying new risk factors for diabetic nephropathy in collaboration with several faculty members in our division.
• Studying new treatment strategies for glomerular disorders.
